Explain module boundaries, dependency flows, and risky imports in the repository.
AI agents call explain_architecture_boundaries to retrieve information from BLUEPRINT MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and analyzes existing architectural metadata to provide advisory information. It retrieves and explains information about code structure and dependencies without side effects. No data is modified, deleted, executed, or at financial risk. This is a classic Read category tool — it helps developers understand existing architecture but does not change anything.
From the tool's definition Tool name 'explain_architecture_boundaries' and description states it 'Explain[s] module boundaries, dependency flows, and risky imports' — purely informational/retrieval operations with no modification, deletion, code execution, or financial impact.
Attacks that exploit this kind of access
Explain module boundaries, dependency flows, and risky imports in the repository. It is categorised as a Read tool in the BLUEPRINT MCP MCP Server, which means it retrieves data without modifying state.
Register the BLUEPRINT MCP server in PolicyLayer and add a rule for explain_architecture_boundaries: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches BLUEPRINT MCP. Nothing to install.
explain_architecture_boundaries is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the explain_architecture_boundaries rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for explain_architecture_boundaries. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
explain_architecture_boundaries is provided by the BLUEPRINT MCP server (vedv7/blueprint.mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
